Hi! I have a clean macOS High Sierra 10.13.5 guest VM and I'm not able to install the current macOS High Sierra 10.13.6 - Update. After downloading the update mac OS asks for a restart. The black screen with the Apple logo appears for a few second the I get the login screen. After the login, the update is still available. Until yesterday I worked with Parallels 13 since today with Parallels 14. The same problem. What can I do to install the update? Thanks for your help!
